Do Octopuses Shed Their Skin? [Explained]

Yes, octopuses do shed their skin. This process is called ecdysis. Octopuses have a thick outer layer of skin that protects them and helps them blend in with their surroundings. They need to shed this skin as they grow to make room for a larger body. 

It is also said that they change the color of the skin, which is a different process, and that is called Chromatophore. They use this process to blend in with their surroundings and to communicate with other octopuses.

They will typically molt multiple times throughout their lifetime, with the frequency of molting varying depending on the species and the individual octopus. Molting is a process that allows the octopus to grow and also to replace old or damaged skin.

These facts are parts of the octopus growth and development process. However, shedding is interesting and makes the octopus lifestyle even more interesting. And if you want to know more, keep on reading.

Do Octopus Shed?

Octopuses do shed their skin as they grow. During the process, the octopus secretes a fluid that loosens and separates the old skin from its body. Then, it will crawl out of the old skin, revealing the new, larger one underneath. 

This process allows them to continually grow and replace damaged or worn skin. Additionally, it also allows them to change color and texture, allowing them to blend in with their surroundings for camouflage.

Do Octopuses Shed Their Suckers?

Octopuses do not shed their suckers. Suckers are a permanent part of the octopus’s anatomy and are used for grasping and manipulating objects. 


Each arm of an octopus has several rows of suckers, which can create a powerful suction force to hold onto prey or other objects. Some species of octopus can regenerate lost suckers, but this is not the same as shedding them.

What Are the Body Parts Of Octopuses That Perform Shedding?

Several parts of an octopus’s body are involved during the shedding process or ecdysis. The octopus will first release enzymes to soften and loosen its existing exoskeleton.

Next, the octopus will use its muscular hydrostats (the octopus’s arms) to separate the old exoskeleton from its body by pulling it off. 

Once the old exoskeleton is removed, the octopus secretes a new one, which will harden and protect its body.

It’s important to note that the octopus does not shed all its skin at once. It will shed the skin of its head and the skin of its body separately.

Also, the eyes, gills and siphons are not shed. A particular skin layer protects them.

Factors That Affect Octopus Shedding

Octopus shedding, also known as ecdysis, is a process that can be affected by various factors. These include:

Environmental factors

The water temperature and salinity of the octopus’s environment can play a role in its shedding process.

The quality of water, including levels of pollution or contaminants, can also affect shedding.

Availability of food, lighting conditions and other environmental factors have an impact on the entire process of shedding.

Biological factors

The age and size of the octopus can affect its shedding process. Different species of octopus may have different shedding patterns and requirements.

One of the significant biological factors of octopus health and nutrition clearly has an effect on the ecdysis. Hormonal changes can also affect the shedding process.

● Human-made factors

Octopuses living in captivity or confinement may have different shedding patterns than wild ones.

Pollution or contamination in the octopus’s environment can affect the shedding process.

Artificial lighting or water conditions can also affect shedding.

Interference with the natural shedding process by humans can also affect the shedding process of octopuses.

It’s important to note that octopus shedding is a complex process that various factors can influence, and a deeper understanding of these factors can help provide better care for octopuses in captivity.

Do Octopuses Die After Shedding?

No, octopuses do not die after shedding. Molting is a normal process of growth and replacement for octopuses, as with other animals with an exoskeleton or outer layer of skin. 


The molting process requires significant energy and can be stressful for the octopus, but it is not fatal. After shedding, the octopus will continue to grow and develop normally. Some species of octopus will molt several times throughout their lifetime, while others will molt only once before they reach maturity.

Importance Of Shedding for Octopus Survival

Shedding, also known as ecdysis, is a critical process for octopuses’ survival for several reasons: 

●      Growth and development: Octopus shedding is necessary for growth and development as it allows the octopus to shed its old skin and grow into a larger, stronger animal. 

●      Protection: Octopus shedding helps to protect the octopus from parasites and predators by shedding off the outer layer of skin, which may have parasites or bacteria attached. 

●      Camouflage: Octopuses have the ability to change color and texture; shedding can help octopus to change their appearance to better match their surroundings, making it more difficult for predators to detect them.

●      Reproduction: Octopus shedding is also necessary for reproduction, as it must shed its skin before it can mate. 

●      Maintenance of health: Octopus shedding helps maintain the octopus’s health and vitality by removing old, damaged skin and allowing the octopus to regenerate new, healthy skin. 

It’s important to note that the shedding process is vital for octopus survival, and a disruption of the natural shedding process can lead to health issues for octopuses. 

In captivity, providing an environment that closely mimics the octopus species’ natural conditions can help ensure that the shedding process occurs smoothly and without complications.


In conclusion, octopuses do shed, much like many other animals. This process, known as ecdysis, is an essential part of the growth and development of these fascinating creatures. 

It allows them to grow larger, repair any damage to their skin, and maintain their camouflage abilities. Next time you see an octopus, remember that it is intelligent and agile and goes through the process of shedding just like other animals.
